      • [crypto/sr25519] #6526 Do not re-execute the Ed25519-style key derivation step when doing signing and verification. The derivation is now done once and only once. This breaks sr25519.GenPrivKeyFromSecret output compatibility. (@Yawning)

      • [types] #6023 Remove tm2pb.Header, tm2pb.BlockID, tm2pb.PartSetHeader and tm2pb.NewValidatorUpdate.
      • Each of the above types has a ToProto and FromProto method or function which replaced this logic.
      • [light] #6054 Move MaxRetryAttempt option from client to provider.
      • NewWithOptions now sets the max retry attempts and timeouts (@cmwaters)
      • [all] #6077 Change spelling from British English to American (@cmwaters)
      • Rename "Subscription.Cancelled()" to "Subscription.Canceled()" in libs/pubsub
      • Rename "behaviour" pkg to "behavior" and internalized it in blocksync v2
      • [rpc/client/http] #6176 Remove endpoint arg from New, NewWithTimeout and NewWithClient (@melekes)
      • [rpc/client/http] #6176 Unexpose WSEvents (@melekes)
      • [rpc/jsonrpc/client/ws_client] #6176 NewWS no longer accepts options (use NewWSWithOptions and OnReconnect funcs to configure the client) (@melekes)
      • [internal/libs] #6366 Move autofile, clist,fail,flowrate, protoio, sync, tempfile, test and timer lib packages to an internal folder
      • [libs/rand] #6364 Remove most of libs/rand in favour of standard lib's math/rand (@liamsi)
      • [mempool] #6466 The original mempool reactor has been versioned as v0 and moved to a sub-package under the root mempool package. Some core types have been kept in the mempool package such as TxCache and it's implementations, the Mempool interface itself and TxInfo. (@alexanderbez)
      • [crypto/sr25519] #6526 Do not re-execute the Ed25519-style key derivation step when doing signing and verification. The derivation is now done once and only once. This breaks sr25519.GenPrivKeyFromSecret output compatibility. (@Yawning)
      • [types] #6627 Move NodeKey to types to make the type public.
      • [config] #6627 Extend config to contain methods LoadNodeKeyID and LoadorGenNodeKeyID
      • [blocksync] #6755 Rename FastSync and Blockchain package to BlockSync (@cmwaters)
    • Data Storage

      • [store/state/evidence/light] #5771 Use an order-preserving varint key encoding (@cmwaters)
      • [mempool] #6396 Remove mempool's write ahead log (WAL), (previously unused by the tendermint code). (@tychoish)
      • [state] #6541 Move pruneBlocks from consensus/state to state/execution. (@JayT106)

    ๐Ÿ”‹ FEATURES

    • ๐Ÿ‘€ [config] Add --mode flag and config variable. See ADR-52 @dongsam
    • [rpc] #6329 Don't cap page size in unsafe mode (@gotjoshua, @cmwaters)
    • [pex] #6305 v2 pex reactor with backwards compatability. Introduces two new pex messages to accomodate for the new p2p stack. Removes the notion of seeds and crawling. All peer exchange reactors behave the same. (@cmwaters)
    • [crypto] #6376 Enable sr25519 as a validator key type
    • [mempool] #6466 Introduction of a prioritized mempool. (@alexanderbez)
      • Priority and Sender have been introduced into the ResponseCheckTx type, where the priority will determine the prioritization of the transaction when a proposer reaps transactions for a block proposal. The sender field acts as an index.
      • Operators may toggle between the legacy mempool reactor, v0, and the new prioritized reactor, v1, by setting the mempool.version configuration, where v1 is the default configuration.
      • Applications that do not specify a priority, i.e. zero, will have transactions reaped by the order in which they are received by the node.
      • Transactions are gossiped in FIFO order as they are in v0.
    • ๐Ÿ‘ [config/indexer] #6411 Introduce support for custom event indexing data sources, specifically PostgreSQL. (@JayT106)
    • [blocksync/event] #6619 Emit blocksync status event when switching consensus/blocksync (@JayT106)
    • [statesync/event] #6700 Emit statesync status start/end event (@JayT106)
    • [inspect] #6785 Add a new inspect command for introspecting the state and block store of a crashed tendermint node. (@williambanfield)

    ๐Ÿ‘Œ IMPROVEMENTS

    • ๐ŸŒฒ [libs/log] Console log formatting changes as a result of #6534 and #6589. (@tychoish)
    • ๐Ÿ”ง [statesync] #6566 Allow state sync fetchers and request timeout to be configurable. (@alexanderbez)
    • [types] #6478 Add block_id to newblock event (@jeebster)
    • [crypto/ed25519] #5632 Adopt zip215 ed25519 verification. (@marbar3778)
    • [crypto/ed25519] #6526 Use curve25519-voi for ed25519 signing and verification. (@Yawning)
    • [crypto/sr25519] #6526 Use curve25519-voi for sr25519 signing and verification. (@Yawning)

    • ๐Ÿ‘ [privval] #5725 Add gRPC support to private validator.
    • [privval] #5876 tendermint show-validator will query the remote signer if gRPC is being used (@marbar3778)
    • [abci/client] #5673 Async requests return an error if queue is full (@melekes)
    • [mempool] #5673 Cancel CheckTx requests if RPC client disconnects or times out (@melekes)
    • [abci] #5706 Added AbciVersion to RequestInfo allowing applications to check ABCI version when connecting to Tendermint. (@marbar3778)

    • [blocksync/v2] #5774 Send status request when new peer joins (@melekes)
    • [store] #5888 store.SaveBlock saves using batches instead of transactions for now to improve ACID properties. This is a quick fix for underlying issues around tm-db and ACID guarantees. (@githubsands)
    • [consensus] #5987 and #5792 Remove the time_iota_ms consensus parameter. Merge tmproto.ConsensusParams and abci.ConsensusParams. (@marbar3778, @valardragon)
    • [types] #5994 Reduce the use of protobuf types in core logic. (@marbar3778)
      • ConsensusParams, BlockParams, ValidatorParams, EvidenceParams, VersionParams, sm.Version and version.Consensus have become native types. They still utilize protobuf when being sent over the wire or written to disk.
    • [rpc/client/http] #6163 Do not drop events even if the out channel is full (@melekes)
    • [node] #6059 Validate and complete genesis doc before saving to state store (@silasdavis)

    • [crypto] #6120 Implement batch verification interface for ed25519 and sr25519. (@marbar3778)
    • [types] #6120 use batch verification for verifying commits signatures.
      • If the key type supports the batch verification API it will try to batch verify. If the verification fails we will single verify each signature.
    • ๐Ÿ‘ [privval/file] #6185 Return error on LoadFilePV, LoadFilePVEmptyState. Allows for better programmatic control of Tendermint.
    • [privval] #6240 Add context.Context to privval interface.
